I upload matlab code of Tracking servo system

bfgs法，求解函数，简单，通俗，易懂，便于优化更改(bfgs)

可以进行matlab滤波，含有多种模板，怎么这么无聊的网站(Matlab filter contains a variety of templates)

一个简单EMD程序 可以很好使用于对EMD分解的初学者，程序中有文字解释(EMD program)

为判断聚类结果质量的好坏，需要一个客观的评价指标来评价聚类结果的合理性。聚类性能评价方法通常分为三种：外部评价法，内部评价法，相对评价法。外部评价法将聚类结果得到类标签和已知类标签进行比较，此评价法的前提是数据集样本的类标签已知(In order to judge the quality of clustering results, good or bad, the need for an objective evaluation to assess the reasonableness of the clustering results. Clustering performance evaluation method is usually divided into three types: external evaluation method, internal evaluation method, relative evaluation method. External evaluation method of clustering results to obtain class labels and the known class labels are compared, the premise of this evaluation method is a class label known sample of the data set)

该程序用于比较KF、EKF、UKF滤波器的不同(The program is used to compare KF, EKF, UKF filter)

改进的粒子群算法--自适应粒子群算法，在普通的粒子群算法里面加入了熵和平均粒距的概念，收敛速度大大提高，而且不容易陷入局部最优，能更有效的解决复杂问题。(improved PSO-- Adaptive PSO. In a normal PSO which joined the entropy and the average particle from the concept of convergence speed, it is not easy to find the global optimum, the more effective solutions to complex problems.)

对采样率进行变换，通过插入零，然后再做低通滤波，实现采样率的提高(Change the sampling rate by inserting zeros, and then do a low pass filter, the sampling rate to achieve the improvement of)

对实验数据的FFT分析，可以显示时域和频域的结果(FFT analysis of the experimental data, can display the results of the time domain and frequency domain)
